A few months ago, I stumbled across a feature-length movie online, but can't remember what (or where) it was. Would greatly appreciate any help identifying this movie!

In the opening scene, there's a naked man (maybe just got out of the shower, I think?) sneaking up on his girlfriend who is sitting on a couch. She has her head turned to her left, away from him. As he gets right up to her from the other direction, she turns her head to see him, and of course, his dick pops right into her mouth for like a second, and then out again. They probably fuck after that, but I don't really remember - it's just that one second surprise BJ that I remember.

No idea who the actor/actress are, unfortunately.

Any ideas on what movie this scene comes from? It was definitely a commercially produced movie, not a tube/amateur thing.

Thanks for your help!
